I am looking for a trapwork part for a 69 Mason & Hamlin Model A. It's the part of the assembly which works the damper pedal. It looks to be made of cast iron. It has the number 65932 stamped into it, which could be a part number. Someone answering email at Mason & Hamlin said they didn't have that part available. Before I take the piece to a local welder for evaluation I thought I would ask here in case one of you can advise me where I might find a replacement. I will attempt to link an image here. Thanks!

Thats a part designed for a reproducer, so I doubt that it is available.Take it to a smith. The break looks clean. The repair should be easily strong enough. That type of damage generally happens during a move.

Mason & Hamlin was not making reproducers in 1969. I do not think that shift levers were ever made of pot metal. Schaff may have some things which are not in the catalog, and in any case, it does no harm to ask.

No they weren't. But many design aspects of the reproducer era continued on in a vestigial fashion. Primary example: the beam configuration. The single beam down the center of the case with branching posts was an adaptation to make room for the player motor and such. This constituted a sacrifice of radial structure. We saw the first Haverill Mason going down the line, and I was dismayed to see that the beams were for a player. This meant that Mason had pulled out the plans for the last produced piano rather than going back further to a more pure design.

I had to make a una corda lever for an older Kawai that was in a church. The cast iron original had snapped and no replacement was available. The only piece that remained was half a lever. I used pinblock material and copied the half that I had and sculpted the rest to facilitate the pedal rod action. I coated it several times with epoxy to give it additional strength. That was about 5 years ago and the piano is still the primary instrument every sunday.
